Abstract

Purpose

To translate and cross-culturally adapt PREP2 into Danish and to investigate the face validity and reliability of Danish PREP2 through cognitive interviewing, Rasch and reliability analyses.

Methods

The Danish PREP2 was translated using a standardized procedure and then pretested following the Three-Steps-Interviews (TSTI) process. A total of 15 myopic children aged 7–14 wearing either orthokeratology lenses (ortho-k) or single-vision spectacles (SVS) were included in pretesting comprising cognitive interviews and Rasch analysis. Data from cognitive interviewing was analysed thematically according to Collins. Rasch analysis was used to pretest the psychometric properties in terms of person- and item-fit statistics. Reliability was assessed via test–retest using Intra-class correlation coefficient (ICC) in the CONTROL study population, which consisted of 60 Danish children aged 7–14 years wearing either ortho-k or SVS.

Results

Fifteen children participated in pilot studies comprising of cognitive interviewing and Rasch analysis and 44 out of 60 CONTROL children participated in test–retest reliability analysis. The translation process resulted in a Danish version of PREP2 corroborating the original. Pretesting highlighted issues in the contextualization of items and in marking responses. Thus, we introduced a digital format with help texts. Cognitive interviewing identified issues in the following Collins’ themes: comprehension (understanding of concepts), judgement (ambiguity of items) and response (selecting answers). Rasch analysis indicated that help texts were useful for clarifying context. The ICC was 0.77 (95% CI: 0.66–0.85).

Conclusions

The cross-cultural adaptation of PREP2 was satisfactory and issues were identified and corrected through pretesting. The test–retest reliability showed substantial consistency. The instrument could be validated in a more generalizable setting in future studies. Trial registration: NCT03246464 (CONTROL study).

儿童视力相关生活质量：丹麦版《儿童屈光不正档案 2》的跨文化适应性和重复测试可靠性

目的将 PREP2 翻译成丹麦语并进行跨文化调整，通过认知访谈、Rasch 和信度分析研究丹麦语 PREP2 的面效度和信度。方法采用标准化程序翻译丹麦语 PREP2，然后按照三步访谈（TSTI）流程进行预测试。共有 15 名 7-14 岁佩戴角膜矫形镜 (ortho-k) 或单光眼镜 (SVS) 的近视儿童参加了包括认知访谈和 Rasch 分析在内的预测试。认知访谈的数据按照柯林斯的方法进行了主题分析。Rasch 分析法用于从个人和项目拟合统计的角度对心理测量特性进行预测试。结果15名儿童参加了包括认知访谈和 Rasch 分析在内的试点研究，60 名研究对象中有 44 名参加了测试-重测可靠性分析。在翻译过程中，丹麦语版本的 PREP2 与原文相吻合。预测试凸显了项目情境化和答案标记方面的问题。因此，我们采用了带有帮助文本的数字格式。认知访谈发现了以下柯林斯主题中的问题：理解（对概念的理解）、判断（题目的模糊性）和回答（选择答案）。Rasch 分析表明，帮助文本有助于澄清上下文。结论 PREP2 的跨文化适应性令人满意，通过预测试发现并纠正了一些问题。测试-再测信度显示出很大的一致性。在未来的研究中，可在更具普遍性的环境中对该工具进行验证。试验注册：NCT03246464（对照研究）。
